CLOSURE.

Specification of Letters Patent.

Patented July '7, 1908.

Application filed. March 19, 1907. Serial No. 363,216.

To all whom it' may concern:

Be it known that I, PETER J. SWEENEY, a citizen of the United States of America, rcsiding at WVindsor, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Closures, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates generally to closures for receptacles, and particularly to a closure having associated therewith retaining means in the form of a holder for preventing the closure from becoming entirely detached from the rece tacle or other vessel with which it is user in connection and thus lost.

The invention consists in the novel construction of the closure and retaining means, and particularly in the peculiar form of connection between the parts permitting rotary movement of the closure independently of the retainer, for the purpose hereinafter set forth.

The invention further consists in other details of construction as will be hereinafter described.

For the purpose of illustrating my invention, I have shown the closure and retaining means as applied to the ordinary form of oilcup, and the single figure in the drawing is a vertical central section through a vessel of this character, illustrating the application of the closure, which is partly in section.

The reference-letter A designates the oilcup, provided with the usual cover section B, a central hollow stem C, and the usual inlet opening D, the latter being internally screwthreaded, as indicated at E, to receive the externally-threaded plug closure F.

G re resents the retaining means, consisting in t is instance of the rod ll connected to the closure and of a length to extend a considerable distance within the oil-cup, and a head or retaining section I, preferably in the form of a loop, as indicated.

Upon the removal of the plug closing the inlet, the retainer is drawn upwardly until the retaining section I abuts against the cup top, the retaining ortion being of a size to prevent its being crawn through the inlet.

The plug is thus connected to the receptacle, while at the same time the fill opening is uncovered sufliciently to permit of the cup being filled.

Upon removing a screw plug of the character set forth it is necessarily rotated, causing the retaining member or means,unless provision is made to guard against it,to also rotate. This movement of the retainer is objectionable, for the reason that in receptacles of the character described the retainer would contact with the central stem during its rotary movement, thus interfering with the removal of the plug cap and causing the bending or breakage of the retainer. To obviate this difficulty, I provide a swivel connection between the retaining means and the plug E, which will permit the closure to be rotated independently of the retainer. The preferable construction is in the form of a universal joint, consisting of a semi-cylindrical head (t formed upon the upper endv of the retainer rod II, and a socket 0 formed in the threaded shank portion of the closure, the lower annular portion (2 of the plug being spun or turned inwardly to form the seat and retaining means for the head member a.

\Vhat I claim as my invention is,

l. The combination with a receptacle having a 'lill o )ening, of a rotatable closure therefor, a retainer for the closure extending from the latter within the receptacle, and a ball and socket joint connection between said retainer and closure.

2. The combination with a receptacle hav- S5 ing an interna.lly-threaded 'Iill opening, of a threaded plug closure for said. opening formed with a socket in its engaging portion, and a retainer for the closure comprising a depending rod having a head at its upper end engaging the closure socket, and an enlargement at its lower end for preventing the withdrawal of the rod from the receptacle upon the removal of the closure.

In testimony whereof I affix my signature in presence of two witnesses.

PETER J. SWEENEY.
